Anti-corrosion ERW Steel Pipe
Anti-corrosion steel pipes are used in petroleum, chimique, gas, heat, sewage treatment, eau, des ponts, steel pipes and other engineering fields, they are divided into the following categories.
3LPE Coated ERW Steel Pipe
Three layer polyethylene anticorrosion is one of the main technical system of buried pipeline corrosion protection domestic and abroad. It has good corrosion resistance, low water absorption and high mechanical strength. It has been used widely in the field of buried water conveyance, gas transmission and pipeline transportation in recent years.
GB/T23257-2009 technical standard for polyethylene anticorrosion coating for buried steel pipeline
SY/T0413-2002 technical standard for polyethylene corrosion resisting layer of buried steel pipeline
DIN30670-2012 technical standards for polyethylene coatings for steel tubes and fittings in Germany
CAN/CSA-Z245.21-M92 Canadian technical standard for polyethylene pipe anticorrosive coating on outer wall
Use: products are widely used in oil pipelines, natural gas pipelines, heating pipes, water pipelines.
3PP (Polypropylène) Tuyau en acier enduit de restes explosifs des guerres
DIN30678 standard technical specification for polypropylene coating for steel pipe and pipe fittings
3Avantages du revêtement PP:
Le tube en acier revêtu de 3PP fait référence à un tube en acier avec trois couches de PP(Polypropylène) enrobage. Il offre une haute résistance électrique, résistance aux acides, résistance aux alcalis, tolérance au sel, isolation électrique, longue durée de vie, endurance thermique et résistance aux chocs. Grâce à la technologie avancée de revêtement des tuyaux en acier, ce type de tuyau en acier plastifié présente des revêtements bien liés.
3Applications de revêtement PP:
Le tuyau en acier à revêtement 3PP convient au transfert de matériaux spéciaux, tels que les matériaux à haute température, car il offre une résistance électrique élevée, résistance aux acides, résistance aux alcalis, tolérance au sel, isolation électrique, longue durée de vie, endurance thermique et résistant aux chocs.
FBE Coated ERW Steel Pipe
FBE coating pipe is Fusion Bonded Epoxy coating steel pipe. It is an externally applied heat resin for pipe. With a form of dry powder at thickness 300-600 microns on to the heated surface of pipe. Once the FBE coated on the pipe surface, the FBE film provides an extremely hard surface with great adhesion to the pipe surface. The FBE layer in a even form and have good resistance to the chemical reaction.
Advantage of the FBE coating pipe:
(1) Convenient to spraying, no pollution, excellent resistance for high temperature (-40°C to 85°C)
(2) High strength and anti-bending performances;
(3) Strong adhesion, good integrity, anti soil stress and wear.
FBE coated steel pipe usually buried in soil and under water between -40°C~85°C temperature.
On the other hand, the defect of the FBE pipe is it doesn’t have good resistance to mechanical performances and humid conditions.
Our FBE coating perform the standards as per SY/T0315, CAN/CSA Z245.20, AWWA C213, Q/CNPC38 etc.
Use: Widely used in land, underwater pipeline anticorrosion.
Polyurethane Insulation Coating ERW Steel Pipe
The polyurethane direct buried heat preservation pipe is a direct buried preheating heat preservation pipe with good heat preservation performance, safety and reliability, and low engineering cost. The buried thermal insulation pipe not only has the advanced technology and practical performance that is difficult to compare with the traditional trench and overhead laying pipeline, but also has obvious social and economic benefits, and is also a powerful measure for heating and energy saving.
It is characterized by a multi-purpose use to prevent the spread of fire and good fire safety performance. Black jacket insulation pipe includes spiral steel pipe, straight seam steel pipe and seamless steel pipe. The outer layer is made of black polyethylene and is called a black jacket insulation tube.
